我想分析整個XML並獲得「的ContactID」，「角色」，「位置」和一些更多的價值爲所有contactid並將其存儲到一個表中。這是如何實現的。

我一直在使用

set serveroutput on; 
DECLARE 
    x XMLType := XMLType(
    ' <changeRequest customerRequestRef="" BTProjectManagementRef=""> 
     <customerOrganisation orgID="ID000001" orgInternalID="29823" resignInstanceType="Source"> 
      <organisationName>BT PLC</organisationName> 
      <contactInfo contactID="ID000002"> 
       <role>CUSTOMER</role> 
       <position /> 
       <fullName /> 
       <telephone /> 
       <fax /> 
       <email /> 
       <contactAddress> 
        <room /> 
        <floor /> 
        <building /> 
        <streetNumber /> 
        <streetName /> 
        <locality /> 
        <city /> 
        <county-state /> 
        <country ISOCountryCode="" /> 
        <postcode /> 
       </contactAddress> 
      </contactInfo> 
     </customerOrganisation> 
     <customerOrganisation orgID="ID000003" orgInternalID="29823" resignInstanceType="Target"> 
      <organisationName>BT PLC</organisationName> 
      <contactInfo contactID="ID000004"> 
       <role>CUSTOMER</role> 
       <position /> 
       <fullName /> 
       <telephone /> 
       <fax /> 
       <email /> 
       <contactAddress> 
        <building /> 
        <streetNumber /> 
        <streetName /> 
        <city /> 
        <county-state /> 
        <country /> 
        <postcode /> 
       </contactAddress> 
      </contactInfo> 
     </customerOrganisation> 
     </changeRequest>'); 


BEGIN 
    For R In (
    SELECT ExtractValue(Value(p),'/changeRequest/customerOrganisation/contactInfo/role/text()') as name 

    FROM TABLE(XMLSequence(Extract(x,'/changeRequest'))) p 
    ) LOOP 

    dbms_output.put_line(r.name); 
    End Loop; 
    Exception 
    When Others then 
    dbms_output.put_line(sqlerrm); 
END;

嘗試，但它拋出一個異常ORA-19025：extractValue一起返回只有一個節點

和XMLSequence的價值 - 是deprecated.Try XMLTABLE XMLTABLE。

訪問XML elmeent屬性使用「@attrname」

select * from xmltable('/changeRequest/customerOrganisation' passing XMLType(
    ' <changeRequest customerRequestRef="" BTProjectManagementRef=""> 
     <customerOrganisation orgID="ID000001" orgInternalID="29823" resignInstanceType="Source">

      <contactInfo contactID="ID000002">

這對我的作品謝謝！我從來沒有想過XMLTable.Now我想創建一個過程，除了xml作爲輸入，並將值獲取到一些變量，以便它可以插入到表中。 – Vishal5364

如果我使用我的完整XML，它將引發錯誤「ORA-01704：字符串文字太長」 – Vishal5364

您的xml很長。你必須將整個XML分解成varcahr2 chunck並將這個塊添加到clob變量中。如果我使用dbms_output.put_line（r.role）， –

你應該添加到customerOrganisation和XMLSequence。因爲你有一些組織爲每個變更請求它的工作原理：

doesnt'給出任何值; – Vishal5364

感謝，更新dbms_output.put_line –

如果我使用我的完整XML，它會引發一個錯誤「字符串文字太長」。 xml大小是140000個字符。 – Vishal5364
